Title: Brake for holding motor vehicle door in open position - is automatically released as door is swung to closed position
Inventor: KLUETING BERND ALFRED DIPL ING
IPC: E05D11/10
Filed: 1991-02-02
Abstract: The door of a motor vehicle is provided with a brake which holds the door in the open position. The brake consists of an arm attached to the hinge pin. The arm is fitted with two radially adjustable blocks (17) which have recesses to receive the rounded heads (21) of brake shoes (18). Each brake shoe (18), can swing about an axis (19), which is parallel to the hinge axis, and the shoe is in contact with the inside surface (23) of a bush. The pivoting of each brake shoe about its axis (19) causes a braking force to be exerted on the surface (23) as the door swings to the open position. The braking force is released when the door swings to the closed position. USE/ADVANTAGE - Brake for motor vehicle door with automatic release.l

Title: Etching rare earth oxysulphide phosphor powder with anhydrous soda - by mixing, calcining in air, cooling and elution with water, useful in CRT screen mfr.
Inventor: WIDMANN HERMANN DR RER NAT
IPC: C09K11/77
Filed: 1991-04-19
Abstract: Pretreatment of a pulverised rare earth oxysulphide phosphor (I), esp. a Tb-activated (I), involves incorporating an additive and heating the mixt. The novel features are that the phosphor is mixed after surface etching with causticised soda, then this mixt. is calcined in air and the calcined prod. is eluted with demineralised water after cooling. Calcination is carried out of 1-5, pref. ca. 3 h at over 300 deg. C, pref. 350-700 deg. C, esp. ca. 500 deg. C. USE/ADVANTAGES - Pretreatment is easy and very few, simple stages are used. (I) is useful for CRT screens and gives better brightness yield and is more uniform than usual.  In an example, a Tb-activated rare earth oxysulphide phosphor powder, e.g. Gd2O2S:Tb, was mixed with causticised soda (i.e. anhydrous soda) in 2-1:1 ratio and calcined ca. 3 h in air at ca. 500 deg. C. The calcined mixt. was cooled and washed with demineralised water to elute the soda and undesired surface deposit. After drying, the phosphor could be used for making a CRT screen. Stimulation with ca. 2kV electrons gave an excellent brightness yield. Green emission was obtd. with a Gd2O2S:Tb phosphor.

Title: Moulded article for use in car interiors - consists of decorative fabric bonded to thermoplastic film which is preformed to shape, and covered by injection moulded shot
Inventor: STORM PETER
IPC: B29C45/14
Filed: 1991-09-28
Abstract: A moulded article partic,. suitable for in car interiors, e.g. a door covering, half shelf etc., consists of an injection moulding with (at least on one side) a fabric (cloth or knitware) decorative layer; it has a plastic film between the moulding and fabric and this is bonded to both. The film is preferably thermoplastic. The product is made by passing together the fabric and film, cutting the laminate obtd. into sheets, placing a sheet in an injection mould, and injecting the shot. The process combines the shape with bonds, whilst the film acts as a barrier to prevent the injected polymer from flowing through the fabric. The cut sheets are best performed before the injection. Such preforming can be carried out by vacuum/thermoforming and it gives the fabric the desired shape, besides preventing pressure peaks from occurring which damage the final appearance. ADVANTAGE - The prod. is simple and inexpensive. It is technologically satisfactory and aesthetically suitable for the applications

Title: Dynamic rigidity adjuster e.g. for vertical hydraulic damper - uses electro-viscous liq. in two chambers sepd. by horizontal plate in hollow cylinder of conductive material
Inventor: UTECHT MANFRED DIPL ING
IPC: H02K5/24

Title: MOSFET with very short channel lengths - uses a multiple implant of dopant in source-drain regions to provide an abrupt, shallow box-shaped dopant profile to minimise punch through
Inventor: KIMURA HIROSHI
IPC: H01L21/336
Filed: 1992-01-14
Abstract: The MOS transistor, consisting of drain/source regions (5) and a gate electrode (3) on top of the gate insulator (2), which defines a channel, also has a polycrystalline Si (polySi) layer (6) on the diffused regions. The dopant, pref. P or As, profile featured pref. has a peak value around 10 power (20) cm-3 at the surface, and a min. depth, pref. about 0.15 micron at which the concn. is about 10 power (19) which is greater than the channel current depth below the surface, after which the concn. rapidly decreases. The gate electrode pref. has an insulation film (4) on sides and top and the polysilicon layer extends onto the insulation layer. After formation of the field-oxide (8) and gate electrode structure (2,3,4) a polySi layer (6) is deposited on the diffusion regions and defined. Then multiple implantations are carried out to build the desired impurity profile. Also claimed is a process in which a first implant is made before the polySi layer (6) has been deposited and after the gate electrode and its insulations have been defined. The first implant is pref. As at 350 KeV with a dose of about 5x10 power (14) cm-2, a second implant, made after deposition and defining the polySi layer, is pref. 10 power (16) cm-2 at 60 KeV. Also claimed is the possible use of a third implant. The dopant is activated by a heat treatment. USE/ADVANTAGE - The profile is intended to approximate that of a constant dopant concn. over a min. depth of about 150nm, and then a sharp decrease of the dopant concn.. This avoids the punchthrough effect between source and drain during operation of the transistor and prevents the diffusion area conductivity being influenced by the gate bias. The profile allows transistors to be made in submicron channel lengths, e.g. down to less than 0.5 micron.
